ABSTRACT:
A lawm trimmer chain saw conversion attachment has a mounting blade which mounts to a chain saw power head in place of the chain bar. The blade supports a housing formed of complementary die-cast halves which contains bevel gears between an input shaft that is chain driven at reduced speed from the saw drive sprocket and an output shaft that couples to the flexible drive shaft of a lawn trimmer frame tube. The frame tube is clamped at its upper end between half-sleeves on the housing halves, and carries a rotary cutter head at its lower end. A D-handle on the frame tube cooperates with the saw handle for convenient manipulation and control. The frame tube is rotatably adjustable and the D-handle is both axially and rotatably adjustable to adapt the assembly to the operator's convenience and to the desired operating angle of the cutter head, e.g., for horizontal lawn trimming, angular edging, sweeping, etc. The handle also rotates down to form a stand for starting or operating the engine with the cutter head elevated. The attachment sprocket is protected by housing walls which receive a snap-on plastic cover which projects toward the saw power head and is adapted to be trimmed to fit the configuration of that head.
